You can also see the container group that you have created in the Elastic Container Instance (ECI) console.

If you purchase a zone-based reserved instance, make sure that it is in the same zone as your serverless Kubernetes cluster. Otherwise, the container group that you create in the Kubernetes cluster cannot use the reserved instance.
